WHAT IS VITAMIN D?
Vitamin D is a nutrient that helps the body absorb calcium and supports normal bone and muscle function.
WHAT IT MEANS
The body can make vitamin D when skin is exposed to sunlight. Food and supplements can also supply it, but needs and intake vary.
A PRACTICAL EXAMPLE
Fortified foods may contribute vitamin D as part of an everyday diet.
IMPORTANT LIMITS
More is not always better. Routine vitamin D blood testing is not recommended for generally healthy adults without a medical reason for testing. A clinician can advise when testing or treatment is appropriate.
FREQUENTLY ASKED QUESTIONS
Does everyone need a test before taking vitamin D?
No. Testing decisions depend on the person’s health and clinical circumstances.
